P& O European Ferries (Irish Sea), Larne“There was an average reduction of 86% in smoke emissions and a more complete combustion of fuel (estimated at between 15-20%). The reduction in smoke is extremely consistent in every vehicle tested with an average value of 86% recorded. This means 86% less environmental pollution, 86% less unburnt fuel and hence a dramatic improvement in fuel consumption and 86% less smoke for the employees of P&O to breathe, hence an improved working environment.”

Stena Line“Tested on a minibus, smoke emissions fell by 48.5% and there appeared to be an increase in power”.

Robert Wiseman Dairies“A reduction in smoke emissions of 39.1% has been realised with a virtually new vehicle…..the use of PD5 will not only help the environment, it will lead to a real-life saving in the cost of fuel (and) a reduction in maintenance costs”
